Really love your pencil shading! I find it hard to do cross hatching for shading (if you could showww me i would appreciate it..even though it should be obvious ^^) anyways.... super cute especially like the first one.

My advice for cross-hatching shading is just to practice. Try to see the first set of lines all going in the same direction. Say if you shaded the hair then the shadow under the nose be sure that all the lines are going in the same direction. It makes a nice clean effect even tho crosshatching isn't clean at all. ^^'
